Description
본 발명은 유기 전계 발광 소자용 재료로서 사용될 수 있는 신규 유기 화합물 및 이를 포함하는 유기 전계 발광 소자에 관한 것이다.The present invention relates to a novel organic compound that can be used as a material for an organic electroluminescence device and an organic electroluminescence device including the same.
1950년대 베르나노스(Bernanose)의 유기 박막 발광 관측을 시점으로 하여, 1965년 안트라센 단결정을 이용한 청색 전기발광으로 이어진 유기 전계 발광(electroluminescent, EL) 소자에 대한 연구가 이어져 오다가, 1987년 탕(Tang)에 의하여 정공층과 발광층의 기능층으로 나눈 적층 구조의 유기 전계 발광 소자가 제시되었다. 이후, 고효율, 고수명의 유기 전계 발광 소자를 만들기 위하여, 소자 내 각각의 특징적인 유기물층을 도입하는 형태로 발전하여 왔으며, 이에 사용되는 특화된 물질의 개발로 이어졌다.The electroluminescent (EL) devices that led to blue electroluminescence using anthracene single crystals in 1965 were followed up with the observation of organic thin film emission from Bernanose in the 1950s. In 1987, And a functional layer of a light-emitting layer. Thereafter, in order to form a high efficiency and high number of organic electroluminescent devices, each organic material layer has been developed into a form in which each organic material layer has been introduced into the device, leading to the development of specialized materials used therefor.
유기 전계 발광 소자는 두 전극 사이에 전압을 걸어주면 양극에서는 정공이 유기물층으로 주입되고, 음극에서는 전자가 유기물층으로 주입된다. 주입된 정공과 전자가 만났을 때 엑시톤(exciton)이 형성되며, 이 엑시톤이 바닥상태로 떨어질 때 빛이 나게 된다. 이때, 유기물층으로 사용되는 물질은 그 기능에 따라, 발광 물질, 정공 주입 물질, 정공 수송 물질, 전자 수송 물질, 전자 주입 물질 등으로 분류될 수 있다.In the organic electroluminescent device, when a voltage is applied between two electrodes, holes are injected into the organic layer in the anode, and electrons are injected into the organic layer in the cathode. When the injected holes and electrons meet, an exciton is formed. When the exciton falls to the ground state, light is emitted. At this time, the material used as the organic material layer can be classified into a light emitting material, a hole injecting material, a hole transporting material, an electron transporting material, an electron injecting material and the like depending on its function.
발광 물질은 발광색에 따라 청색, 녹색, 적색 발광 물질과, 보다 나은 천연색을 구현하기 위한 노란색 및 주황색 발광 물질로 구분될 수 있다. 또한, 색순도의 증가와 에너지 전이를 통한 발광 효율을 증가시키기 위하여, 발광 물질로서 호스트/도펀트 계를 사용할 수 있다.The luminescent material can be classified into blue, green and red luminescent materials according to luminescent colors and yellow and orange luminescent materials to realize better natural colors. Further, in order to increase the color purity and increase the luminous efficiency through energy transfer, a host / dopant system can be used as a light emitting material.
도펀트 물질은 유기 물질을 사용하는 형광 도펀트와 Ir, Pt 등의 중원자(heavy atoms)가 포함된 금속 착체 화합물을 사용하는 인광 도펀트로 나눌 수 있다. 이때, 인광 재료의 개발은 이론적으로 형광에 비해 4배까지 발광 효율을 향상시킬 수 있기 때문에, 인광 도펀트 뿐만 아니라 인광 호스트 재료들에 대한 연구도 많이 진행되고 있다.The dopant material can be divided into a fluorescent dopant using an organic material and a phosphorescent dopant using a metal complex compound containing heavy atoms such as Ir and Pt. At this time, since the development of the phosphorescent material can theoretically improve the luminous efficiency up to 4 times as compared with the fluorescence, the phosphorescent dopant as well as phosphorescent host materials are being studied extensively.
현재까지 정공 주입층, 정공 수송층, 정공 차단층, 전자 수송층 재료로는 NPB, BCP, Alq3 등이 널리 알려져 있으며, 발광층 재료로는 안트라센 유도체들이 보고되고 있다. 특히, 발광층 재료 중 효율 향상 측면에서 장점을 가지고 있는 Firpic, Ir(ppy)3, (acac)Ir(btp)2 등과 같은 Ir을 포함하는 금속 착체 화합물이 청색(blue), 녹색(green), 적색(red)의 인광 도판트 재료로 사용되고 있으며, 4,4-디카바졸리비페닐(4,4-dicarbazolybiphenyl, CBP)은 인광 호스트 재료로 사용되고 있다.To date, NPB, BCP and Alq 3 have been widely known as the hole injecting layer, the hole transporting layer, the hole blocking layer and the electron transporting layer material, and anthracene derivatives have been reported as the light emitting layer material. Particularly, metal complex compounds containing Ir such as Firpic, Ir (ppy) 3 , (acac) Ir (btp) 2 and the like having advantages in terms of efficiency improvement of the light emitting layer material are blue, green, 4,4-dicarbazolybiphenyl (CBP) is used as a phosphorescent dopant material for red phosphorescent dopants.
그러나 종래의 유기물층 재료들은 발광 특성 측면에서는 유리한 면이 있으나, 유리전이온도가 낮아 열적 안정성이 매우 좋지 않기 때문에, 유기 전계 발광 소자의 수명 측면에서 만족할 만한 수준이 되지 못하고 있다. 따라서, 성능이 뛰어난 유기물층 재료의 개발이 요구되고 있다.However, conventional organic material layers are advantageous from the viewpoint of light emitting properties, but their thermal stability is not very good due to their low glass transition temperature, and thus they are not satisfactory in terms of lifetime of the organic electroluminescent device. Therefore, development of an organic layer material having excellent performance is required.
본 발명은 유기 전계 발광 소자에 적용할 수 있으며, 정공, 전자 주입 및 수송능, 발광능 등이 모두 우수한 신규 유기 화합물을 제공하는 것을 목적으로 한다. It is an object of the present invention to provide a novel organic compound which can be applied to an organic electroluminescent device and which is excellent in hole, electron injection, transporting ability, and light emitting ability.
또한, 본 발명은 상기 신규 유기 화합물을 포함하여 낮은 구동 전압과 높은 발광 효율을 나타내며 수명이 향상되는 유기 전계 발광 소자를 제공하는 것을 또 다른 목적으로 한다.It is another object of the present invention to provide an organic electroluminescent device including the novel organic compound and exhibiting a low driving voltage and a high luminous efficiency and having an improved lifetime.
